Prices of Short Oligos

2 up to 17-mers (short chains) are charged as a 17-mer.

This is due to the fact that a significant portion of the short oligo price is represented by the column price on which the synthesis takes place. Upon calculating the oligo price as a product of the price of the base and length, the resulting price would not cover the price of the column. Therefore short oligos are charged as a 17-mer with no additional fee.
